Abstract: A heat shrinkable wrap-around sleeve comprises a heat shrinkable sheet with a heat stable strip welded on one end.  The free end of the heat stable strip is overlapped on the outer side of the opposite end of the sheet and welded thereto by heating applied directly on the outer side.  This allows the material of the strip to differ in its properties from the material of the sheet, so that the nature of welded closure can be tailored to particular applications.  It also allows manufacture of sleeves having hold-down adhesives applied on them to be  conducted with greater ease  and economy.   The sleeve can be manufactured using continuous welding, for example by heated wedge welding.

Filed: 1992-02-20
Granted: 1999-09-07
Abstract: This invention relates to a process for the conversion of waste and/or fresh polymers, especially polyolefins, into lower hydrocarbons by vaporising them in a fluidised bed of particulate material in the presence of a fluidising gas at a temperature from 300-690°C. The lower hydrocarbons can be further converted to useful olefins, paraffins or waxes by steam cracking the lower hydrocarbons, preferably in the absence of any catalyst. This is an effective and efficient method of recycling waste polymers.

Title: Apparatus and robust method for detecting tones
Inventor: DIGHE RAJIV S
IPC: H04Q1/45
Filed: 1993-02-16
Granted: 1997-08-12
Abstract: A robust tone detector is realized by applying a single taper, which provides a relatively narrow bandwidth filter, to a received signal and, then, performing a Discrete Fourier Transform of the tapered signal. The result of theFourier transform is used to obtain an estimate of energy in the frequency domain of the expected tone. A prescribed selection algorithm based on the relationship of the received signal energy in the time domain and the energy estimate in the frequency domain is used to determine whether a valid tone has been received. Robustness of the tone detector is improved by performing a plurality of Discrete Fourier Transforms of the single tapered version of the received signal at a corresponding plurality of frequencies relative to the nominal frequency of an expected one or more tones. A further improvement in the tone detector is obtained by dynamically adjusting tone acceptance thresholds based on a measure of channel impairments.

Title: Organic pesticide
Inventor: WILSON WALTER R
IPC: C05G3/60
Filed: 1993-06-23
Granted: 1998-01-20
Abstract: This invention relates to a totally organic refined wax based pesticide which is a longer-lasting, environmentally safe, pesticide which effects a physical change in the organisms' ecosystem thereby mechanically disrupting its ability to function. The pesticide is coupled with a naturally-produced central nervous system stimulant and other naturally-produced irritants, antioxidants, insect repellants, scents, and soil nutrients. Through the synergy between the physical contraction of the wax base, containing capsaicin, as it dehydrates coupled with the higher vapor pressure (volatility) of the scent package, leads so a natural migration of the scent package to the surface of the waxy base thereby maintaining effectiveness for a longer period of time with a decreased frequency of application. The figure shows product preparation through a recirculating system via water inlet (44) leading to outlet (28) controlled by valves (38 and 32) providing product to collection tube (34) or heater inlet (42). Oil phase is fed into inlet (2), thence to vortex mixer (6).

Granted: 2004-04-27
Abstract: A cap composed of a snap-on, tamper-evident closure is formed with a central sleeve (28). The bottom of the sleeve is closed off by a removable plug (46). The exterior of the closure is formed with a bead (58). The water dispenser is provided with an adapter consisting of an open-bottom outer sleeve (11) into which the neck (24) of the container with the closure (26) in place thereon fits. Centrally disposed in the outer sleeve is a dispenser tube (16). When the container is inverted its neck is inserted in the outer tube (11). As the neck and cap are lowered, the dispenser tube enters the cap sleeve (28) and attaches to the plug (46). Continued lowering of the container causes the plug (46) to slide out of the sleeve (28) so that liquid in the container flows out through the dispenser tube (16) into the dispenser. When the container is lifted, the plug (46)(which has been attached to the dispenser tube (16)) is pulled back into its original sealed position (fig. 1). The plug and cap are at all times discrete. The exterior skirt of the plug and the interior wall of the well sleeve (28) are seamless.

Title: Method and apparatus for controlling microorganisms
Inventor: CHRISTENSEN RONALD J
IPC: C02F1/467
Filed: 1993-07-20
Granted: 1999-11-16
Abstract: Water in a process water system, such as a cooling tower or pulp and paper processing plant, is treated to destroy biological microorganisms by diverting the portion of the water flowing through the system to a side stream. In the side stream, chemicals are added such as halide ions or sodium chlorite. The water is then passed through an electrolysis unit or a UV radiation unit to oxidize the precursor to form an active oxidant. Advantageously, the pH of the side stream can be lowered to significantly improve the oxidization of the halide ions. When a very small portion of the flow rate is passing through the side stream, the acid added does not significantly alter the pH of the entire system. In a preferred embodiment, the acid added is phosphonic acid which acts as an antiscalant. Also included in the present invention is a method to inject oxidant precursors into a process water system through an oxidant generation station.
